Be it known that I, AUBREY WARDMAN, a 17 in the county of Los Angeles and'State of alifor nia, have invented new and useful Imprvements in Lime-Test Connectors, of.which the following is a specification.

My invention relates to means for conveniently and quickly attaching a testinginstru ment to electric-circuit wires so that the line vice for'that purpose. I accom lish this object by the connector describe hereiri and 1lluStrated in the'accompanying drawings, in

Figure lis a perspective view of a connector,- showing one of the line-wires and one of the test-instrument-wires secured -therein. Fig. 2is a section on the line 2 2 of Fig. 1 'With the. instrurhent-Wire omi tted.

In the drawings, 3 is a plate of resilient conductive matenal, which is stamped or out to form spring-tongues 4, which are prefer ably bent downwardly below the body of the then u wardly through the slot 5, ormedinthe %ody of the late by the cutting of the tongues, and t en downwardly, preferably to within the slot, andthen upwardlso as to leave the inner ends rojecting s1ightly above the body of the p ate and also pro&ecting up'wardly and toward each other. hese tongues are in oppositely-disposed pairs, and the connecter may consist of a body with a single air of tongues, or. as many pairs as may be. esired. I have found by ractical test of the device that a connector wit two pairs of spring-tongues, as shown in Fig. 1, produces a satisfactory device and is cheap and efficient. As shown in the drawings, the free ends of the ton ues lie adjacent to each other and above t e body, so that the c0nnector may be slipped over theliie-wire 6 and betWeen connected to the othercircuitwir in like manner. sbon as the circuit is tested the connectors are easily and quickly disconnct ed from the -circuit'wires and can be applied elsewhere.

' It will be observed that in practicaluse the body of the connector Willbe in a vertical plane the instrument connections bespringtongues will always keep them in good elect'ncal contact and that the connector .ldwt e circuit-wi1e, so that the pull onithe Cannot be accidentafly disengagedfrom'the circuit-Wires.,- The sprin 'tongues could be seoured 'to the 'body at t e ends; if dsired,

insteadof being made integral; but I prefei inaking them -1htegral, as shown, as it is cheaper so to do. y
